我想从父代码调用无限循环脚本。
from subprocess import Popen
import subprocess
import os
import sys
proc=subprocess.Popen([sys.executable, os.getcwd()+'/A.py'],shell=False, stdout=subprocess.PIPE)
print(proc.communicate())
print('Hi')
我的脚本是：
import time
def main():
while True:
print('HI2')
time.sleep(3)
if __name__ == '__main__':
main()`
但它不起作用，Popen会阻止脚本。我的意思是为什么print（'Hi'）语法不起作用。
答案 0 :(得分：1)
proc等待out, err = proc.communicate()
完成。然后它返回子进程的输出。
在这个示例中，out是打印在stdout上的输出，错误是stderr上的输出：
communicate()如果您不需要输出，请跳过breed [people p]
breed [party1 p1]
breed [party2 p2]
breed [party3 p3]
party1-own [vote]
party2-own [vote]
party3-own [vote]
